Glazing Silicone in South Oxhey
We cover South Oxhey for glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Glazing silicone for homes and businesses in South Oxhey
Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. The old sealant comes out, the joint is cleaned and new silicone goes in. We work on shower screens, glass-to-frame joints and glass balustrade bases, and people most often call us about water getting into a conservatory at the joints and silicone pulling away from the glass.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The process
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in South Oxhey. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Mention any tricky access

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or drop us an email.

Surface by surface
Rooflights
Rooflight glazing joints are cut out and renewed. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Old sealant is removed carefully from the glass and reseal with glazing silicone.
Signs you need glazing silicone in South Oxhey
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead, and water gets between the layers.
Any of these means the joints need attention:
- Leaks from the base of a shower screen
- Water tracking down the inner face of the glass
- Mouldy sealant around glass panels
- Leaks where conservatory glass meets the frame
Schools such as Greenfields Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Common questions in South Oxhey
Can you do glazing silicone in South Oxhey?
Yes, South Oxhey is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.
Is parking an issue for glazing silicone in South Oxhey?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Do you reseal glass shower screens?
We can. We remove the old silicone carefully before cleaning and resealing.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Glazing silicone in South Oxhey: local notes
Historic houses like Headstone Manor (about 2.4 miles south-east) are a reminder that the area around South Oxhey has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Oxhey Chapel, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Carpenders Park station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Well-known places in the area include Hilfield Castle (3.3 miles north-east) and Heath Robinson Museum (1.9 miles south). Green spaces nearby include Tumbling Bay and Harrow Weald Common.
Leave it or put it right?
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in South Oxhey.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
